The automobile interior material of the present invention has a surface layer that is a slightly harder layer having a Shore D hardness of approximately 55 to 85, and a back layer that is a soft laminated sheet having a Shore D hardness of approximately 15 to 50. And a releasable backing material is adhered to the back surface of the laminated sheet, and the surface of the laminated sheet is provided with a concavo-convex pattern. With the backing peeled off, it is used by a vacuum molding method on a molding substrate composed of hard pads, resin-coated thick letters, corrugated cardboard, etc., and the heat-sensitive adhesive film is activated by heating during vacuum molding. It is possible to adhere to the substrate at the same time as vacuum forming. The molded product thus obtained is used for automobile trims, door trims, and the like. Further, when synthetic resin foam such as urethane foam or polystyrene foam is used as the base material, the weld process can be easily performed by the welder process.

In this case, since the surface is a hard layer, the weld shoulder does not shine and a very good weld line is obtained. In any of these cases, since there is a layer with a small amount of plasticizer or a slightly higher layer on the surface, there is no squeezing back at the time of heating and gloss return of the weld line, and since the back surface is a soft layer, adhesion to the substrate is more It is certainly done.

The thickness ratio between the front surface layer and the back surface layer of the laminated sheet is preferably in the range of about 1: 2 to 1: 5 based on experimental results. That is, the thicker the hard layer on the surface is, the smaller the drawdown during vacuum forming (the degree to which the laminated sheet hangs down due to the heat applied during vacuum forming) is preferable, but conversely when the uneven squeezing pattern is applied to the surface, the squeezing pattern is less likely to appear. Moreover, it is necessary to set a long weld time during the welding process. Defects such as curling and waving of laminated sheets cannot be eliminated, and they do not adapt to subtle unevenness and unevenness of the molding base material.
Also, the thicker the soft layer on the back surface, the better the conformability of the molding base material to the unevenness and unevenness and bending corners, and the more likely the uneven pattern of the surface layer is to appear, but the drawdown during vacuum forming tends to be excessive, There are drawbacks such as easy to get back and gloss, and easy to get gloss back of the weld shoulder during welding.

Therefore, as a result of considering all of these processing conditions and use conditions, it is optimal that the thickness ratio between the front surface layer and the back surface layer is in the range of about 1: 2 to 1: 5. The ones contribute significantly to the weight saving for the purpose of energy saving and the labor saving of the production process, and can achieve the intended purpose.
